What is the main research question?
What is the main research question?
Asthma treatment using short-acting beta agonists (SABAs) alone is compared to treatments including inhaled corticosteroids (ICS) with either SABAs or long-acting beta agonists (LABAs).
What treatments are compared?
What treatments are compared?
Researchers compared the effectiveness of SABA alone, ICS with LABA (formoterol), and ICS with SABA for treating asthma.

Study Notes
Inhaled Reliever Therapy for Asthma
- Study compared different inhaled reliever therapies for asthma
- Focused on short-acting β agonists (SABA), inhaled corticosteroids (ICS) combined with formoterol, and ICS combined with SABA
- Analyzed data from 27 randomized clinical trials with a total of 50,496 adult and pediatric patients (mean age 41.0 years, 40% male)
Findings
- Reduced Exacerbations:
- ICS-formoterol significantly reduced severe exacerbations (risk ratio [RR] 0.65, 95% CI 0.60-0.72) compared to SABA alone
- ICS-SABA also showed a reduction in severe exacerbations (RR 0.84, 95% CI 0.73-0.95) relative to SABA alone
- Improved Asthma Control:
- ICS-formoterol and ICS-SABA both led to improved asthma control compared to SABA alone. (Significant improvement in MID scores and respective risk differences)
- Indirect Comparison (ICS-Formoterol vs. ICS-SABA):
- ICS-formoterol exhibited a greater reduction in severe exacerbations (RR 0.78, 95% CI 0.66-0.92) than ICS-SABA
- Safety:
- Neither ICS-formoterol nor ICS-SABA showed an increased risk of serious adverse events compared to SABA alone (high/moderate certainty)
- Certainty of Evidence:
- Evidence for reduced exacerbations and improved control is high certainty for both ICS combinations.
- Evidence for ICS-formoterol vs. ICS-SABA and their safety effects is moderate to high certainty.
